Application tiled June 17, 1912. Serial No. 704,230.

To (lil "Ir/tom (t muy con/ern Be it known that I. ANDREW J. CnisT, a citizen if tht` llnited States. residing at morita, in the county of Alfalfa and State of Oklahoma, have invented certain new and useful Improvements in Motor-Car Attachments. of which thtl following is a specification. reference being had therein to the accompanying drawing.

This invention relates to a power attachment to be used in connection with an aut-omobile, and has for its object the production of an efficient motor which may be driven by the rear wheels of an automobile.

Another object ot this invention is the production of an etticient mechanism which may be operated with the rear drive wheels of an automobile, whereby power may be transported from the automobile to some place distant from the machine for driving a churn, washing machine, or any other desired device.

lith these and other objects in view, this invention consists of certain novel construetions, combinations, and arrangements ot' parts,A as will be hereinafter fully described and claimed.

In the dra\vings:- `igure 1 is a side elevation of the automobile shown connected to theI power attachment. Fig. 2 is an enlarged transverse section through the power attachment. Fig. 3 is a detail perspective of the brake shoe used in connection with the power attachment Fig. 4t is a detail perspective of the lower end of the brake lever which engages the brake links for throwing the brake shoes in engagement with-the driving wheels of the power attachment. Fig. 5 is an enlarged sectional view of the upper corner of the frame of the power attachmei'it. Fig. is a detail perspective of one end of the anchor brace used in connection with the 'trame for the power attachment.

The present invention is especially adapted for use in connection with automobiles o' other motor driven vehicles. and the device is preferably 'arricd in the floor of a garage or other automobile house. and consists of a rectangular frame formed of a plurality of vertically extending members l, connected by means of transversely extending upper and lower braces 2. These upper and lower braces are braced by means ot diagonally extending braces 3, whiciL braces form a substantially V-shaped structure connected at their inner ends as at 4 to constitute a journal supporting portion upon which the journal 5 is mounted. The vertically extending members 1 of the frame are provided with angle feet 6 for allowing the same to be conveniently attached to the upper and lower members 2.

A central supporting shaft 7 is journaled within the journals 5, and a driving wheel 8 is carried by the shaft near each end of the frame, and in such a position to receive the rear drive wheels t) ot' an automobile. The i rims of the wheel are formed concave, as indicated at l0 in Fig. 4 to receive the tires of the rear wheel of an automobile. A drive pulley 11 is carried by the end of the shaft 7, and around this pulley 1l passes a driving belt l2 which driving belt may pass to any desired place, for driving a dynamo or other machine.

The, main frame is provided with a pair of tra nsverscly extending portions 14. which portions are braced by means otthe diagonal braces 15.- A plunger 1T is carried by each of the side members and this plunger normally held in an extended position by means of a coil spring 18. A tread portion 1S) is carried by the upper end of the plunger and the lower end of the plunger rod 17 is provided with a pair of laterally extendingr ears 30. which ears receive the ends of the operating links 21 of the brake mechanism. 'lllc opposite ends ot the operating links 2l are pivotally connected to the brake shoes 22. which brake shoes are pivotally secured to the upper members 2 of the frame. by means of journals 23. These journals 253 are held in engagement with thc members 2 by means of bolts 24. The under faces are so formed as to conform to the contour of the outer face of the drive wheels 8.

It will be seen that by depressing the brake operating plungers. the brake shoes Q2 will be thrown so as to firmly grip the outer faces ol the driving wheels 8, and thereby prevent the further rotation of the wheels after the automobile has been removed from the driving wheels 8. The automobile is braced in a tirm position in engagement with the driving wheels 8, by means of bracing hooks Q5, which hooks have their upper ends QG straddling the axles of the automobile. and thereby hold the same in a steady position upon the driving wheels 8.

From the foregoing description il' Will be eeen that a very rllieient and durable power ataelimem, inten prfsnlne'ed upon which avosnobile may eiiieiently aol so as to impe: r Winry nim. ement to ilie drive Wheels 5, ii. nell a nimmer es #lo drive the drive )Mlleir Il, i
